A GPU-accelerated path tracing renderer for three.js built on three-mesh-bvh and WebGL 2. It provides physically based rendering with GGX materials, textures, normal maps, emission, environment maps, and tiled rendering.

Use cases

• render photorealistic 3D scenes in the browser
• path trace glTF/GLB models with physically based materials
• add raytraced lighting and depth of field to a three.js scene
• render interior scenes with environment maps and volumetric fog
• build a drag-and-drop 3D model viewer with high-quality rendering

When to choose

• you need physically based, high-quality offline-style rendering in WebGL
• your project already uses three.js and three-mesh-bvh
• you want GPU path tracing without native dependencies

When to avoid

• you need real-time rasterization performance for games
• your target browsers lack WebGL 2 support
• you need production-grade rendering features like full spectral rendering or denoising pipelines
